Use of Corneal Power-Specific Constants to Improve the Accuracy of the SRK/T Formula

Purpose: To evaluate the effect of average corneal power (K) and axial length (AL) in a data-adjusted A-constant for improving the refractive outcome in the Sanders–Retzlaff–Kraff (SRK)/T formula. Design: Retrospective, consecutive, case series. Participants: A total of 637 patients (637 eyes) who underwent uncomplicated phacoemulsification with implantation of the Acrysof IQ (IQ; Alcon, Fort Worth, TX; 314 eyes) or Akreos AO (AO; Bausch & Lomb, Rochester, NY; 323 eyes) intraocular lens (IOL) by a single surgeon. Methods: The correlation among the K, AL, and predicted refractive error in the SRK/T (Read more...)
